Am searching for parents of my grmother Johanna LYONS SHEEHAN b. 1870's in Ireland (Co Cork) and came to US as a teenager. Her mother is listed as Joan SULLIVAN on her death certificate; her siblings, Pete LYONS and Maria LYONS also came to Columbus Ohio in the 1890s. Would appreciate any help or conncetions. Thank you, Molly Placko
